ABSTRACT:
Disclosed herein is an outboard motor including a lower unit comprising a propeller adapted for rotation under water, and a swivel bracket adapted for mounting to a transom bracket for vertical tilting movement about a generally horizontal axis. A kingpin assembly including a pivot shaft is supported by the swivel bracket for rotation about a generally vertical axis, the pivot shaft having fixed thereto a pinion and means for supporting the lower unit. A rack is located below the generally horizontal axis and engages the pinion. The rack is supported by the swivel bracket to afford generally horizontal movement of the rack, which horizontal movement effects rotation of the pivot shaft and the lower unit about the vertical axis. Hydraulically activated plunger mechanisms connected to the rack are provided for effecting horizontal movement of the rack and thereby affording control of the rotation of the lower unit about the vertical axis.
